Represents a collection of a set of key and value pairs. Each key in the MixedCollection
must be unique, the same key cannot exist twice. This collection is ordered, items in the
collection can be accessed by index  or via the key. Newly added items are added to
the end of the collection. This class is similar to <a href="Ext.util.HashMap.html" rel="Ext.util.HashMap" class="docClass">Ext.util.HashMap</a> however it
is heavier and provides more functionality. Sample usage:
<pre class="prettyprint"><code>var coll = new Ext.util.MixedCollection();
coll.add('key1', 'val1');
coll.add('key2', 'val2');
coll.add('key3', 'val3');

console.log(coll.get('key1')); // prints 'val1'
console.log(coll.indexOfKey('key3')); // prints 2
</code></pre>

<p>
The MixedCollection also has support for sorting and filtering of the values in the collection.
<pre class="prettyprint"><code>var coll = new Ext.util.MixedCollection();
coll.add('key1', 100);
coll.add('key2', -100);
coll.add('key3', 17);
coll.add('key4', 0);
var biggerThanZero = coll.filterBy(function(value){
    return value > 0;
});
console.log(biggerThanZero.getCount()); // prints 2
</code></pre>

<br><p><b><u>DOM events from ExtJs <a href="Ext.Component.html" rel="Ext.Component" class="docClass">Components</a></u></b></p>


<br><p>While <i>some</i> ExtJs Component classes export selected DOM events (e.g. "click", "mouseover" etc), this


<p>is usually only done when extra value can be added. For example the <a href="Ext.view.View.html" rel="Ext.view.View" class="docClass">DataView</a>'s
<b><code><a href="Ext.view.View.html#click" rel="Ext.view.View#click" class="docClass">click</a></code></b> event passing the node clicked on. To access DOM
events directly from a child element of a Component, we need to specify the <code>element</code> option to
identify the Component property to add a DOM listener to:</p>

<pre><code>new Ext.panel.Panel({
    width: 400,
    height: 200,
    dockedItems: [{
        xtype: 'toolbar'
    }],
    listeners: {
        click: {
            element: 'el', //bind to the underlying el property on the panel
            fn: function(){ console.log('click el'); }
        },
        dblclick: {
            element: 'body', //bind to the underlying body property on the panel
            fn: function(){ console.log('dblclick body'); }
        }
    }
});

<p>This option is useful during Component construction to add DOM event listeners to elements of <a href="Ext.Component.html" rel="Ext.Component" class="docClass">Components</a> which
will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:
<pre><code>new Ext.panel.Panel({
    title: 'The title',
    listeners: {
        click: this.handlePanelClick,
        element: 'body'
    }
});

<p></div></li>
</ul><br></p>

<p>
<b>Combining Options</b><br>
Using the options argument, it is possible to combine different types of listeners:<br>
<br>
A delayed, one-time listener.
<pre><code>myPanel.on('hide', this.handleClick, this, {
single: true,
delay: 100
});</code></pre>
<p>
<b>Attaching multiple handlers in 1 call</b><br>
The method also allows for a single argument to be passed which is a config object containing properties
which specify multiple events. For example:
<pre><code>myGridPanel.on({
    cellClick: this.onCellClick,
    mouseover: this.onMouseOver,
    mouseout: this.onMouseOut,
    scope: this // Important. Ensure "this" is correct during handler execution
});

<p>This is commonly used by Ext.Components to bubble events to owner Containers. See <a href="Ext.Component.html#getBubbleTarget" rel="Ext.Component#getBubbleTarget" class="docClass">Ext.Component.getBubbleTarget</a>. The default

access the required target more quickly.</p>

//  Add functionality to Field&#39;s initComponent to enable the change event to bubble
initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {

//  We know that we want Field&#39;s events to bubble directly to the FormPanel.
getBubbleTarget : function() {
